    • An optical unit includes an optical emitter receiving an optical emitter current, an optical sensor receiving an optical sensor current and light from the optical emitter and in response thereto outputting at least one signal indicating relative movement between the optical unit and an optical code scale, and an optical sensor current detector comparing the optical sensor current to a reference value. In response to the optical sensor current being different than the reference value, the optical sensor current detector outputs an optical sensor current detector signal. The optical sensor current detector signal indicates the presence of a contaminant in a light path from the optical emitter to the optical sensor, and is used to regulate the current to the optical emitter so as to counteract the negative effects of the contaminant in the light path.
    • 光学单元包括接收光发射器电流的光发射器,接收来自光发射器的光学传感器电流和光的光学传感器,并且响应于此输出至少一个指示光学单元和光学代码量表之间的相对运动的信号,以及 将光学传感器电流与参考值进行比较的光学传感器电流检测器。 响应于光学传感器电流不同于参考值,光学传感器电流检测器输出光学传感器电流检测器信号。 光学传感器电流检测器信号指示在从光发射器到光学传感器的光路中存在污染物,并且用于调节到光发射器的电流,以便抵消光路中污染物的负面影响 。
